Abstract
An electric cable (especially a medium voltage power cable) with fire integrity and low smoke and fume properties and with good long term resistance to moisture has a three-layer sheath. The inner layer is of a polyethylene with a density of at least 0.938 and provides the main barrier against moisture penetration. The intermediate layer is an inorganic flexible tape, preferably of copper or other metal, and serves mainly to preserve integrity under fire conditions. The outer layer preferably surrounds the intermediate layer with a slight clearance and is of a low-smoke-and-fume polymeric composition.
